[OE-core] FILEXEXTRAPATHS advice in wiki doesn't seem to be strictly followed

[Robert P. J. Day]

  here:

http://www.openembedded.org/wiki/Migrating_metadata_to_OE-Core

there is some apparently hard and fast advice:

"Use FILESEXTRAPATHS to extend file search path: Modifications to
FILESPATHPKG and/or FILESPATH should be replaced by prepending to
FILESEXTRAPATHS; in addition, you no longer need to define THISDIR
(and should not do so). For example, to add a directory to be searched
for patches and other files which is named with PN, do the following
(note the immediate evaluation operator := and trailing colon, these
are important):

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"


  but it seems the use of that variable is a bit fast and loose:

$ grep -r FILESEXTRAPATHS *
... snip ...
meta/recipes-graphics/mesa/mesa-common.inc:FILESEXTRAPATHS_append := "${THISDIR}/mesa:"
meta/recipes-graphics/mesa/mesa-git.inc:FILESEXTRAPATHS_prepend := "${THISDIR}/mesa-git:"
meta/recipes-graphics/xorg-xserver/xserver-xorg-lite_1.11.2.bb:FILESEXTRAPATHS_append := "${THISDIR}/xserver-xorg:${THISDIR}/xserver-xorg-${PV}:"
meta/recipes-qt/qt4/qt4-native_4.7.4.bb:FILESEXTRAPATHS =. "${FILE_DIRNAME}/qt-${PV}:"
meta/recipes-qt/qt4/qt4-tools-nativesdk.inc:FILESEXTRAPATHS =. "${FILE_DIRNAME}/qt-${PV}:"
meta/recipes-qt/qt4/qt4-native_4.8.0.bb:FILESEXTRAPATHS =. "${FILE_DIRNAME}/qt-${PV}:"
meta/classes/utils.bbclass:	extrapaths = (d.getVar("FILESEXTRAPATHS", True) or "")
$

  does this matter?
